Aluminum or magnesium alloy casting sand core removing device and method

Abstract

The invention relates to a sand core removing device and method, in particular to an aluminum or magnesium alloy casting sand core removing device and method. The aluminum or magnesium alloy casting sand core removing device and method solve the problems that in the prior art, thin-walled complex aluminum or magnesium alloy casting sand core removing is difficult and the removing period is long, and are used for efficiently removing thin-walled complex aluminum or magnesium alloy casting sand cores. The aluminum or magnesium alloy casting sand core removing device comprises a casting compressing assembly and a mechanical vibrating assembly, and further comprises an ultrasonic wave removing assembly. The aluminum or magnesium alloy casting sand core removing method comprises the steps of soaking, vibration and ultrasonic wave impacting. The aluminum or magnesium alloy casting sand core removing device is simple in structure, low in energy consumption and easy to control. The aluminum or magnesium alloy casting sand core removing device and method integrate the effects of chemical dissolution, vibration crushing and ultrasonic wave cavitation removing, and are good in casting cleaning effect, high in efficiency and applicable to efficiently removing thin-walled complex aluminum or magnesium alloy casting sand cores.

Description

technical field [0001] The invention belongs to a sand core cleaning device and method, and is suitable for efficient cleaning of sand cores for aluminum or magnesium alloy complex thin-walled castings. Background technique [0002] With the continuous development of aerospace, national defense, automobile industry and other industries, castings are becoming more and more lightweight and precise, and the demand for magnesium-aluminum alloy thin-walled castings is increasing. Most magnesium-aluminum alloy thin-walled castings often have complex inner cavity structures or thin, curved, and long hole structures, and the sand cores are often combined sand cores, which makes the post-casting cleaning of castings very difficult. [0003] At present, common sand core cleaning methods can be divided into two categories: wet method and dry method: wet cleaning includes hydraulic sand cleaning, water blast sand cleaning, electro-hydraulic sand cleaning and chemical sand cleaning, etc....
